为了给老式热处理电阻炉大修以及电炉生产提供经验,北京市技术交流站与一些单位合作,总结前一阶段使用新型耐火材料改造电炉节约能源所取得的经验和教训,根据节能原理,分析常用耐火、保温材料的性能和价格,在综合技术经济指标定量分析的基础上,联合设计制造了一台硅酸铝纤维毡和水泥膨胀珍珠岩复合炉衬的节能电炉。经空载运行、各项指标实测以及近五十余次开炉生产实践表明,与老式电炉比,该炉具有节电、高效、安装维修方便、造价低等优点。一、热处理电炉节能途径热处理电阻炉是由型钢框架,一定厚度
In order to provide the experience of overheating old electric resistance furnace and electric furnace production, Beijing Technology Exchange Center, in cooperation with some units, summarizes the experiences and lessons learned from using the new refractory materials to save energy in the electric furnace in the previous stage. According to the principle of energy conservation, Insulation material performance and price, based on the quantitative analysis of technical and economic indicators, jointly designed and manufactured an energy-saving electric furnace of aluminum silicate fiber felt and cement expanded perlite composite lining. The operation of no-load operation, the measured indicators and nearly 50 times of blast furnace production practice shows that, compared with the old electric furnace, the furnace has the advantages of energy saving, high efficiency, easy installation and maintenance, low cost. First, heat treatment furnace energy-saving way Heat treatment furnace resistance by the steel frame, a certain thickness
